Welcome to this guide on creating Ansible Playbooks. Ansible is an open-source automation tool that makes your systems and applications easier to deploy.
What is a Playbook?
Playbooks are the files where Ansible code is written. Playbooks are written in YAML format, which means they are highly readable and easy to understand for administrators and developers alike.
A Basic Example
Here is a basic example of how an Ansible Playbook looks. It targets a group of servers and updates the apache package:
---
- name: Update web servers
hosts: webservers
remote_user: root
tasks:
- name: Ensure apache is at the latest version
yum:
name: httpd
state: latest
- name: Write the apache config file
template:
src: /srv/httpd.j2
dest: /etc/httpd.conf
By defining your infrastructure as code, you can easily track changes, version your playbooks, and automate repetitive tasks across thousands of servers seamlessly.
